Question

我使用gr_moodtools创建了一个模块gr-freqAdaptiveOFDM，我创建了一个文件signal_field.h，它将定义用于块“Packet Header Generator”的函数formatter（）。为此，我需要将其称为freqAdaptiveOFDM.signal_field（）。formatter（），但是当我调用它时，我得到一个错误，说freqAdaptiveOFDM没有属性signal_field。

定义signal_fields的文件是：

signal_field_impl.h

#ifndef INCLUDED_FREQADAPTIVEOFDM_SIGNAL_FIELD_IMPL_H
#define INCLUDED_FREQADAPTIVEOFDM_SIGNAL_FIELD_IMPL_H

#include <freqAdaptiveOFDM/signal_field.h>
#include "utils.h"

namespace gr {
namespace freqAdaptiveOFDM {

class signal_field_impl : public signal_field
{
public:
    signal_field_impl();
    ~signal_field_impl();

    bool header_formatter(long packet_len, unsigned char *out,
            const std::vector<tag_t> &tags);

    bool header_parser(const unsigned char *header,
            std::vector<tag_t> &tags);
private:
    int get_bit(int b, int i);
    void generate_signal_field(char *out, frame_param &frame, ofdm_param &ofdm);
};

} // namespace freqAdaptiveOFDM
} // namespace gr

#endif /* INCLUDED_FREQADAPTIVEOFDM_SIGNAL_FIELD_IMPL_H */

signal_field.h

#ifndef INCLUDED_FREQADAPTIVEOFDM_SIGNAL_FIELD_H
#define INCLUDED_FREQADAPTIVEOFDM_SIGNAL_FIELD_H

#include <freqAdaptiveOFDM/api.h>
#include <gnuradio/digital/packet_header_default.h>

namespace gr {
namespace freqAdaptiveOFDM {

class FREQADAPTIVEOFDM_API signal_field : virtual public digital::packet_header_default
{
public:
    typedef boost::shared_ptr<signal_field> sptr;
    static sptr make();

protected:
    signal_field();
};

} // namespace freqAdaptiveOFDM
} // namespace gr

#endif /* INCLUDED_FREQADAPTIVEOFDM_SIGNAL_FIELD_H */

我修改了我的swig文件：

#define FREQADAPTIVEOFDM_API

%include "gnuradio.i"
%include "freqAdaptiveOFDM_swig_doc.i"

%{
#include "freqAdaptiveOFDM/mapper.h"
#include "freqAdaptiveOFDM/signal_field.h"
%}

%include "gnuradio/digital/packet_header_default.h"

%include "freqAdaptiveOFDM/mapper.h"
%include "freqAdaptiveOFDM/signal_field.h"

GR_SWIG_BLOCK_MAGIC2(freqAdaptiveOFDM, mapper);

%template(signal_field_sptr) boost::shared_ptr<gr::freqAdaptiveOFDM::signal_field>;
%pythoncode %{
signal_field_sptr.__repr__ = lambda self: "<signal_field>"
signal_field = signal_field.make;
%}

我该怎么做？

提前多多感谢！

向GNURADIO模块添加属性
